MELBOURNE, Australia (AP) Serena Williams stuck out a fist in mock triumph and mouthed "C'mon," careful not to push her point too far.
The 33-year-old Williams was closing in on her 19th Grand Slam singles title, her 16th straight win over Maria Sharapova and her sixth Australian Open championship when she was docked a point by the chair umpire for hindrance - for yelling in celebration too early when she thought she'd hit a service winner.
She didn't let that, or another early celebration on match point, or a hacking cough that made her sick, become distractions. Instead, Williams maintained her composure to beat Sharapova 6-3, 7-6 (5) on Saturday night to continue her 100 percent record in finals at Melbourne Park and move closer to Steffi Graf's record of 22 major titles in the Open era.
